In the 1980s, the demand for increasing package density grew up, and it affected the power consumption of NMOS ICs. (b). Lambda based design rules reason of explaining lambda properly is to make design itself independent of both process and fabrication and to permit the design to be re-scaled at future date when the fabrication tolerances are shrunk. 208 0 obj <>/Filter/FlateDecode/ID[<48FE7C5CF79B24DD9E48162AAD102D68><9FC71E313AC29A4DA491CBA5FC7B03E3>]/Index[197 25]/Info 196 0 R/Length 69/Prev 902390/Root 198 0 R/Size 222/Type/XRef/W[1 2 1]>>stream VLSI Technology, Inc., was an American company that designed and manufactured custom and semi-custom integrated circuits (ICs).
